Yes Sir they are Max Wedge intake ports.. And I'm running the Mopar Performance tunnel ram. I actually seen where they dynoed a 470 cubic inch low block 400 base motor that made right at the same horse power as the ported Wilson single four barrel intake. I think the intake was a Indy intake. The tunnel ram didn't have the max wide ports. But performed very well. With in a few little numbers of the ported Wilson. That's why I was thinking of the 270 jead. Cam pro profile is LSA 112 .674 lift with a 1.6 rocker and a 296 duration with a 5500 JW converter.
